IMPROVEMENT IN TAKE-UPDEVICES FOR S EWING-MACHIN ES.

S pccificationforming part of Letters Patent No. 216.994, dated July 1,1879 application filed March 13, 1879.

To all whom it may concern:

Be it known that I, GEORGE W. BAKER, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and usefulImprovements in Take-Up Devices for Sewing-Machines; and I do herebydeclare the following to be a full, clear, and exact de scription of theinvention, such as will enable others skilled in the art to, which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification. 7

My invention relates to a take-up device for sewing-machines; and itconsists of the mechanism hereinafter described and claimed.

In the drawings, Figure 1 shows a device constructed according to myinvention as it appears when the needle-bar is at its upward throw, andFig. 2 represents the same when the needle-bar is at its lowest point.

In each figure is shown the thread passing through. I

A is the faceplate of a sewing-machine, to which is attached thedouble-ended take-up lever B. This is in the shape substantially of arocking lever, having a longer and a shorter arm, B B

The thread, as it comes from the spool, is first passed through an eyeor loop in the shorter arm, B from thence through a similar loop or eyein the longer arm, B and from thence down to the needle. I

The take-up lever B may be either fixedly or adjnstably attached to theface-plate A, although I prefer an adjustable attachment, as shown inthe drawings, which is effected by pivoting the take-up lever B upon aslotted plate, 0, through the slot of which an attaching-screw passesfor attaching the entire device to the face-plate A.

' Between the pivot 0, upon which the takeup lever B rocks, and the endof the longer arm, B is attached. the link D, which directly connectsthe take-up lever B with the needle-bar D.

When thus connected it will be apparent that the vertical reciprocatingmovement of the needle-bar will, through the link-connection justspecified, impart a rocking motion to the take-up lever B, substantiallyas indicated in the drawings.

The desired character and extent of rocking movement of the take-up maybe regulated and determined by a proper adjustment of the take-up leverin its position upon the face-plate A.

It will be observed that one extremity of the link is pivoted to thelong arm of the double-end lever, and that the other extremity isloosely connected with the pivot a, secured on the needle-bar, andworking in the vertical slot 1) formed in the face-plate.

What I claim is l. The combination, with a face-plate provided with thevertical slot and a needle-bar, of the double-end lever, a device whichsecures the latter in pivotal position on the faceplate, and the link,one of whose extremities is pivoted to said lever, together with a pivotwhich connects the opposite end of the link to theneedle-bar and worksin said faceplate slot, substantially as set forth.

2. The combination, with'a faceplate provided with the vertical slot anda needlebar, of the doubleend lever having a long and a short arm, adevice which secures the lever in pivotal position on the face-plate,and a link, one of whose extremities is 'pivoted to said long arm of thelever, together with a pivot which connects the opposite extremity ofthe link to the needle-bar and works in said face-plate slot,substantially as set forth.

3. The combination of the needle-bar, the double-end lever, and thelink, whose opposite extremities are pivoted respectively to theneedle-bar and one arm of the lever, together with the face-plate, theplate to which the lever is directly pivoted, and the adjusting devicewhich secures said lever-pivoted plate at different vertical points onthe faceplate of the machine, substantially as set forth.

4. The combination of'the needle-bar, the doubleend lever having alongand a short arm, the link whose opposite extremities are pivotedrespectively to the needle-bar and the In testimony whereof I havesigned my name long arm of the leverytcgether with the faceto thisspecification in the presence of two subplate, the plate to which thelever is directly scribing witnesses.

pivoted said plate being formed with a ver- GEORGE W. BAKER.

' tical slot, and the set-screw which works in'i Witnesses:

the latter and vertically adjusts the take-up, JNo. OROWELL, J12,substantially as setforth. 1 WILLIAM E. DONNELLY.
